I regularly have to meet with people in multiple time zones, anywhere from 3 to 15 people. I'm looking for a solution that will allow people to indicate their availability and then schedule the meeting based on the most popular availability. Please Help!

It makes it easy to plan something by providing options and voting to decide where and when to meet. You can send invites quickly and even get access to features like saving the event in your phone calendar and get directions to the location.
